Professional Disjointed footage (not consecutive frames in playback)

Mu DJI P3P was at 7th. flight yesterday. Was shooting some images in 4K, recording some video clips. The playback mode view a result of a video not in
coherent picture frames. To me it looks like a buffer of frames are collecting hum delayed time of 4.2 sec, then video playback roll as normal, but only for a period of 3-6 sec, so it on again. No matter if I use Nero Video 2015 Adobe Premiere video editor, same result. This is the first recording 3P3 with jumping frames, as I will mention it.
This is a screen dump of flight recorder data:
105
00: 01: 45,000 -> 00: 01: 46,000
HOME (8.0553,58.1411) 2015.6.16 13:43:40
GPS (8.0538,58.1406,20) Hb: 211.1 Hs: 0.0
ISO: 800 TV: 5000 EV: IR: F2.8

Looks like ISO 800 is "overkill", as this footage was done in Clearly sunny day!
